Abstract
The random-vortex method is used to investigate the flow around two circular cylinders in side-by-side and tandem arrangements. The numerical scheme incorporates the vortex-in-cell method with overlapping meshes and is a combination of various procedures which have developed previously. The computations are carried out at a Reynolds number of 200 where the near-wake is predominantly two-dimensional and laminar and vortex shedding is known to occur on a single cylinder. The computed flow fields reproduce the various flow regimes observed experimentally at high subcritical Reynolds numbers with the corresponding force and frequency characteristics. The method may handle a general arrangement of circular cylinders. © 1992.
